BINDER.

SPECIFICATION forming part of Letters Patent No. 767,157, dated August9, 1904.

Application filed December 16, 1903. Serial No. 185,341. (No model.)

To all whom it may concern.-

Be it known that I, LEON M. LESLIE, a citizen of the United States,residing at Leslie, county of Bergen, State of New Jersey, have inventeda new and useful Improvement in Binders, of which the following is aspecification.

My invention relates to the novel construction of a binder-frame, whichis simple and durable in construction and capable of being readilyadjusted, and consists of suitable jaws having means for operating saidjaws to open and close the same.

It further consists of novel details of construction, all as will behereinafter fully set forth.

Figure 1 represents a top plan View of a binder-frame embodying myinvention, showing the parts in closed position. Fig. 2 represents a topplan view of a binder-frame, showing the parts in open position. Fig. 3represents a sectional view on line :23 m, Fig. 2. Fig. 4 represents asectional view on line 7/9 Fig! on line 2 2, Fig. 1.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates a binder-frame embodying myinvention, having a back 2, which is formed in any suitable manner andof any suitable material and in the present instance is shown slightlycurved.

and provided with the ends 3, which may be integral with the same orsuitably attached thereto, while movably mounted on the said back arethe jaws 4, which in the present instance are longitudinally immovable,but can move laterally in order to increase or decrease the spacebetween the same in order to permit the insertion or removal of theloose leaves.

5 designates a longitudinally extending threaded rod, which is supportedin bearings 8 and on which is movably mounted a nut 6, and the end ofsaid rod is pivotally mounted in the lug 7.

9 and 10 designate bars, one end of the same being secured to one of thejaws 4, while the opposite end of said bars are pivotally attached Fig.5 represents a sectional view together, as at 11, and also to the nut 6,the bar 10 having the slot 12 therein.

13 and 14 designate bars, one end of each of which is attached to thejaw 4 and the opposite end of the same being pivoted together at 15 andbeing attached to the lug 7, in which the rod 5 is pivotally mounted, itbeing seen that the bar 9 is provided with a slot 16 and that the bars13 and 14 each have a headed pin 17, which are adapted to slide in theslots 12 and 16, the construction just described being substantially thelazy-tongs principle.

Suitably connected with the jaws 4 are the binding posts or supports 18,which are preferably telescopic in construction, whereby this supportwill extend between the jaws whether the latter are in open or closedposition, and Ipreferably make the supports staggeredthat is to say,that the outer or larger portion of a support is connected with one jawand that the next support has the outer or larger portion connected withthe opposite jaw. If desired, I may employ a suitable guide for thejaws, which are also provided with the end pieces 19 in order that theends of the book will always be closed.

20 designates suitable hinges, to which the leaves or covers of the bookare attached. The end of the longitudinally-extending rod is providedwith a suitable end 21 for engagement with a suitable key and properopening in the end walls 3.

The operation will be readily seen. By turning the rod 5 in the properdirection the nut 6 is moved on the rod-as, for example, the parts beingin the position seen in Fig. 1 and the rod is turned the nut 6 is causedto move thereon toward the center and in so moving carries with it thepivoted ends of the bars 9 and 10, the ends of which being attached tothe jaws cause the same to separate and at the same time force out theother ends of the arms 13 and 14 by reason of the connection with thepin 17. It will thus be seen that the jaws are in the position seen inFig. 2, the supports 18 opening in a suitable manner, as will be seen.By a reverse turning of the rod 5 the bars draw together the jaws 4. Itwill thus be seen that a strong endurable construction results and thatthe bars are easily operated to in crease or decrease the size of thebook, as desired.

It will be evident that variouschanges may be made by those skilled inthe art which will come within the scope of my invention, and I do not,therefore, desire to be limited in every instance to the exactconstruction herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a binder, aback, jaws movably mounted on said back, alongitudinally-extending threaded rod, a traveler on said rod, a pair ofarms each pivotally connected at one end to said traveler and at itsopposite end to one of said jaws, a second. pair of arms pivotally connected together at one end and each having its opposite end pivotallyconnected to one of said jaws, said second pair of arms crossing said.iirst-named pair and being operatively connected thereto to receivemotion directly there from. p

2. In abinder, aback, jaws movablyniounted on said back, alongitudinally-extending threaded rod, a traveler on said rod, a pair ofarms each pivotally connected at one end to said traveler and at itsopposite end to one of said jaws, a second pair of arms pivotallyconnected together at one end and each having its opposite end pivotallyconnected to one of said jaws, a stationary support for the pivotalpoint of said second pair of arms and means whereby said second pair ofarms is operatively connected with said first-named pair.

3. A binder, comprising a back, jaws movably mounted on said back, aplurality of pairs of arms crossing each other, pivotal connectionsbetween the outer ends of said arms and said jaws, pivotal connectionsat the inner ends of said arms, a longitudinally-disposed threaded rodand a traveler on said rod pivotally connected with one pair of saidarms, the second pair of said arms having pivotal and sliding connecionwith said first-named pair.

4.. In a binder, aback, jaws movably mounted on said back, a threadedrod suitably supported, a traveler on said rod, a pair of arms havingone end of each pivotally attached to each other and to said travelerand the op posite ends attached each to one of said jaws and a secondpair of arms having one end of each pivotally attached to the other andthe opposite end pivotally attached to the jaws, said pairs of armscrossing each other and being positively supported at their points ofjuncture.

5. In a binder, aback, jaws movably mounted on said back, a threaded rodsuitably supported, a traveler on said rod, a pair of arms having oneend of each pivotally attached to each other and to said traveler andthe opposite ends attached each to one of said jaws and a second pair ofarms having one end of each pivotally attached to the other and theopposite end pivotally attached to the jaws and slots in each of onepair of arms and pins in each of the other pair of arms adapted to beseated in said slots.

6. Ina'binder, a back, jaws movably mounted on said back, a threaded rodsuitably supported, a traveler on said rod, a pair of arms having oneend of each pivotally attached to each other and to said traveler andthe opposite ends attached each to one of said jaws and a second pair ofarms having one end of each pivotally attached to the other and theopposite end pivotally attached to the jaws, means for operativelyconnecting said two pairs of arms, and supports extending between saidjaws in open or closed position.

7. A binder comprising a back, jaws movably mounted on said back, aplurality of pairs of arms crossing each other, pin-andslot connectionsbetween saidv arms at their points of crossing, pivotal connectionsbetween the outer ends of said arms and said jaws, pivotal connectionsat the inner ends of said arms, a longitudinally-disposed threaded rodand a traveler on said. rod, pivotally connected with one pair of saidarms.
